A simple way to enable in-app purchases using cryptocurrencies.

A video clip about this method (A little different in appearance but the same in function):

Using this program's method, you can make in-app purchases using cryptocurrencies.

Users only had limited time to finish payment.

The user picks the method of payment, and then the app shows the price in that currency. Users have to send that amount of money to the address. Users have to paste [TXID] of payment in the program. The app will verify the payment with the registered price at that time.
